xtensa: add separate property sections option
It is currently not possible to correctly match .xt.prop information for sections with identical VMA. Allow creation of separate property sections in the BFD. Add assembler option --separate-prop-tables to allow creation of separate property sections. 2018-06-04 Volodymyr Arbatov <arbatov@cadence.com> bfd/ * elf32-xtensa.c (elf32xtensa_separate_props): New global variable. (xtensa_add_names): New function. (xtensa_property_section_name): Add new parameter separate_sections, use it to choose property section name. (xtensa_get_separate_property_section): New function. (xtensa_get_property_section): Invoke xtensa_get_separate_property_section to get individual property section if it exists, common property section otherwise. (xtensa_make_property_section): Pass elf32xtensa_separate_props to xtensa_property_section_name. gas/ * config/tc-xtensa.c (elf32xtensa_separate_props): New declaration. (option_separate_props, option_no_separate_props): New enumeration constants. (md_longopts): Add separate-prop-tables option. (md_parse_option): Add cases for option_separate_props and option_no_separate_props. (md_show_usage): Add help for [no-]separate-prop-tables options.
